Question

I’ve been trying to figure out where my error is in this particular function.
It’s very similar to a posted function online with a few minor tweaks. Anyway, I have a specific url in the variable $PAYMENTPAGE->ipa_url. I’m trying to post to this and simply have the return data be a die(‘test’) to verify the connection is going through properly.
Instead I keep getting a blank page.

I have managed to get it working using the curl extension but would prefer to simply use streams as they work out of the box with any extensions. I know the connection is being made, because I was receiving exception errors which I fixed, but now I’m just having trouble figuring out why no information is being returned from the post.

function doPostRequest($url, $data, $optional_headers = null)
{
    $params = array('http' => array(
                'method' => 'POST',
                'content' => $data
             ));
    if ($optional_headers !== null) {
        $params['http']['header'] = $optional_headers;
    }
    $ctx = stream_context_create($params);
    $get_stream = true;
    try{
        $fp = @fopen($url, 'rb', false, $ctx);
        if (!$fp) {
             throw new Exception("Problem creating stream from $url, \n\t".implode("\n\t", error_get_last()));
        }
        $response = @stream_get_contents($fp);
        if ($response === false) {
           throw new Exception("Problem reading data from $url, \n\t".implode("\n\t", error_get_last()));
        }
        $get_stream = false;
    } catch(Exception $e){
        mcFatal("Error(".date('Y-m-d h:i:s').'):'.$e->getMessage()."\n");
    }


    if($get_stream){
        return false;
    }

    return $response;
}
